The Object REXX programming language is an object-oriented scripting language initially produced by IBM for the operating system OS/2 and later for Microsoft Windows. It is a follow-on to and a significant extension[a] of the "Classic Rexx" language originally created for the Conversational Monitor System (CMS) component of the operating system VM/SP and later ported to Multiple Virtual Storage (MVS),[b] OS/2 and PC DOS.
On October 12, 2004, IBM released Object REXX as free and open-source software, giving rise to Open Object Rexx (ooREXX), now available for various operating systems: Linux, Solaris, Windows. This implementation includes a Windows Script Host (WSH) Scripting Engine for Rexx. The released sources however didn't include the classes for SOM and Workplace Shell (WPS) support.
- Object REXX and Open Object Rexx do not include all of the new feature of ANSI standard Rexx, although they have many new features of their own.
